This paper theoretically analyzes the propagation characteristics of magnetostatic waves （MSWs） in magnetic film under normal nonuniform bias field.The dynamic magnetization of MSWs under the nonuniform field of parabolic profile is calculated in detail.Calculation results indicate that
under nonuniform bias field of appropriate profile
MSW amplitude can be increased by comparison with the case of uniform bias magnetic field
thereby
the diffraction effect of guided optical waves from the MSWs is also enhanced.
